Macroscopic Consumption Matrix for On-line Energy-efficient Route Guidance

In this paper the authors introduce a macroscopic fuel consumption matrix for on-line use in energy- efficient route guidance in an urban traffic network. This matrix represents the dependency of the average consumption per road link on two macroscopic parameters: the mean vehicle speed along a trajectory and the cumulated vehicle acceleration – a sum of positive speed differences along a trajectory. The matrix can be used for any link of an urban road network in on-line applications for energy efficient route guidance. The required input for on-line applications based on this macroscopic matrix are GPS traces measured with navigation devices. It is described how this macroscopic consumption matrix is generated: an empirical microscopic consumption matrix is combined with microscopic simulated speed and acceleration data of vehicles. The empirical microscopic consumption matrix has been derived from off-line single vehicle data from floating cars. The microscopic speed and acceleration data have been generated by means of a traffic flow simulation. Based on these data, the dependency of the fuel consumption on the cumulated vehicle acceleration is discussed.
